More commonly referred to as a Hole-in-One, you’ll need to complete any of the Par 3’s in one shot. The other holes are just too far out of reach. This is probably easiest on the second hole. Go to Challenge Play and select the first Par 3 (second hole) for a very favorable pin position at the back of the green. Obviously you’ll want calm winds and practice your shot a few times before actually shooting. The practice shot shows where the ball will land, but not where it will roll too.
I aimed straight at the hole, a little bit before the pin. Don’t count on the ball bouncing a lot then slowly trickling in, it’ll likely bounce 2-3 times, hit the pin and drop straight down. So, you’re likely lining up your practice shot closer to the pin than you would in a golf sim.
